I am not a breeder, but I am a buyer and a businesswoman...so I'll stick to advice I know about.

1) you will find that many (most?) buyers won't want to deal with someone who is under 18 years old. no offense but there it is.

2) the advice about checking local laws is crucial! you don't want to get in trouble with your local laws, the IRS, or your insurance companies (homeowner's insurance or business insurance).

3) if you are dealing with high-end morphs especially....find a vet who is a fully qualified reptile specialist. This is true for any pet snake as well, but if this is an investment you don't want to mess around or you could see your money fly away if you have egg-binding, illness, or other health troubles. Also read some books and get well-versed in methods of getting babies to eat.

4) you must be willing to commit your time first to your customers, second to your snakes, and third to everything else. One bad transaction, if you fail to immediately make it right to the customer's satisfaction, can end your career as a breeder. Assume that as a fact and you'll be a good seller! Be prepared to lose money on a sale to preserve your reputation - even if you think the buyer is mistaken. Never let a dispute get personal. This takes a great deal of self control and takes practice.

Good luck! Being your own boss is great...if you are willing to go the extra mile.
